Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Gather safety equipment (gloves and safety glasses).

2. Lift the Vehicle

Use a hydraulic jack to lift the vehicle and secure it with jack stands.
Ensure the vehicle is stable before working underneath.

3. Inspect and Replace Suspension Components

Shock Absorbers/Struts:
1. Remove the wheel to access the suspension components.
2. Disconnect the upper and lower mounting bolts for the shock absorber or strut using a socket set.
3. Remove the shock absorber/strut from the vehicle.
4. Install the new shock absorber/strut in reverse order, ensuring to torque the bolts to manufacturer specifications.
Control Arm/Bushings:
1. Inspect control arm bushings for wear or damage; replace if necessary.
2. Remove the control arm by unbolting it from the frame and the steering knuckle.
3. Install new bushings if required, then reattach the control arm.

4. Reassemble and Lower Vehicle

Reattach the wheel and torque the lug nuts to the specified value.
Lower the vehicle back to the ground.
